Abstract
Underwater Wireless Sensor Network (UWSN) is newly developed branch of Wireless Sensor network (WSN). UWSN is used for exploration of underwater resources, oceanographic data collection, flood or disaster prevention, tactical surveillance system and unmanned underwater vehicles. UWSN uses sensors of small size with a limited energy, memory and allows limited range for communication. Due to multiple differences from terrestrial sensor network, radio waves cannot be used over here. Acoustic channel are used for communication in deep water, which has many limitations like low bandwidth, high end to end delay and path loss. With the above limitations while using acoustic waves, it is very important to develop energy efficient and reliable protocols. Energy efficient communication in underwater networks has become uttermost need of UWSN technology. The main aim nowadays is to operate sensor with smaller battery for a longer time. This paper will analyse various routing protocols in the area of UWSN through simulation. This paper will analyse Depth Based Routing (DBR), Energy Efficient Depth Based Routing (EEDBR) and Hop by Hop Dynamic Addressing Based (H2-DAB) protocol through simulation. This comparison is carried out on the basis of total consumed energy, end to end delay, path loss and data delivery ratio.
Highlights
Underwater Wireless Sensor Network (UWSN) is a newly emerging wireless technology which is providing the most promising mechanism used for discovering acoustic environment very efficiently for many scenarios like military [1], emergency and commercial purposes [2]
In this paper we have compared the state of the art routing protocols in UWSN
While designing any www.ijacsa.thesai.org routing protocol one should keep in view the requirement for specific application
Summary
UWSN is a newly emerging wireless technology which is providing the most promising mechanism used for discovering acoustic environment very efficiently for many scenarios like military [1], emergency and commercial purposes [2]. In acoustic communication bandwidth is very limited which is less than 100KHz. In underwater scenarios, sensor nodes are usually considered static but it is considered that they may move from 1 to 3 meter/second due to flow of water[10]. Once data is received at any of the sink data is forwarded to concerned node through radio transmission[11] While using those routing protocols which requires higher bandwidth, usually has higher delay at the nodes end[12]. As we know that acoustic communication does not support higher bandwidth so using routing protocols that are used in terrestrial network will not perform good due to it higher delay and high energy consumption.
